' CHANNEL TYPE WEATHER STRIP Filed July 15, 1955 A ""IIIII EL MER D. BHRR/NGER.

Patented Oct. 22, 1935 UNITED STATES PATENT OFFICE '7 Claims.

In the art of Weatherstrip installation today, there is commonly used in conjunction with socalled French windows, or windows in which the swinging casement type of sash are employed, what are known as channel Weatherstrip members or devices that are located upon the sill of the window frame below the swinging sash.

These channel Weatherstrip devices, called channels, are designed to receive and carry off water which may leak past the Weatherstrip meansintermediate the sash and the channel, so as to prevent the water or moisture from reaching the inside of the window or sash.

In order to prevent water thus received and passing off from the channel from contacting with the wood of the sill portion of the frame, which in time would cause a rotting away of this wood, it has been proposed heretofore to dispose below said channel, and on the sill portion of the window which would otherwise receive the water, a metal plate, this plate being virtually a bottom plate for the channel and protecting the wood of the window in the manner above noted.

The present invention involves a special form of bottom plate which may bemade from metal or any other suitable material, the same being constructed in a peculiar way to coact with the fastening screws or members that secure the channel to the window sill so that the bottom plate will be pushed into its proper position relative to the bottom portion of the channel incident to the attachment of the channel to the sill by the said screws or fastening means. And where the channel is of the type which is frequently used today, namely that construction which is intended to be seated in the angle formed between the stool of the window frame and the main sill thereof, the bottom plate construction which 00- operates with the screw or other fastening means is designed to have the additional function or effect, according to this invention, of tending to force such a channel member snugly into the angle between the stool and main window sill above referred to.

In carrying out the foregoing, according to my invention, I avail of a peculiar resilient V-shaped flange at the inner edge of the bottom plate, said flange adapted to cooperate with a depending flange on the bottom portion of the channel member and with the screw or other fastening means to accomplish the objects above noted.

Additionally, the said flange is peculiarly formed so as to provide a lower biting edge capable of digginginto the wood of the main sill, or otherwbase portion of the window frame on which it may be mounted as an incident to the firm fastening down of the channel member on said sill, an air tight and water tight connection being obtained between the bottom plate and sill in this manner, having the especial advantage of eliminating the necessity of using a calking material or substance between the bottom of the channel and the top of the base or sill portion of the window on which it is mounted.

With the foregoing and other objects in view, certain adaptations of my invention are illustrated in the accompanying drawing, but it is to be understood that I do not wish to be limited to the exact constructions depicted therein as the latter may be modified in certain respects within the purview of my invention, and the scope of the appended claims.

In said accompanying drawing:-

Figure 1 is a sectional viewof the lower edge portion of an in-swinging casement sash of a French window showing Weatherstrip equipment 20 including that of the present invention, the bottom plate construction comprising the novel feature of the invention being associated with a channel member located .at the angle between the stool of the window frame and the main base sill.

Figure 2 is a View similar to Figure 1 showing a different construction of window frame and sill;

also, the application of the invention to a slightly so different construction of channel member.

Figure 3 is a perspective view of the bottom plate showing the resilient V-flange formation more clearly.

Figure 4 is a fragmentary view somewhat similar to Figure 2, but less full in illustration, depicting a modified adaptation of the invention, wherein the resilient flange is up-turned instead of down-turned, as is true in respect to the construction of Figures 1 to 3 inclusive.

Figure 5 is a View similar to Figure 3, but showing the modified form of the bottom or metal plate employed beneath the channel according to the construction of Figure 4.

In Figure. 1 the base or main sill of the window frame is designated A. The stool at the inner edge of the sill A is designated B, and the swinging sash of the French windowis denoted C. Beneath the lower edge of the sash C is located the channel I consisting of a base having the inner Vertical flange 2, and the outer vertical flange 3. A hook Weatherstrip member 4 cooperates with the lip 5 of the flange 3 and a rain drip member 6 connects with the portion 1 of the hook weatherstrip-member 4. i

The Weatherstrip equipment comprising the parts 4, 5, 6, and I, does not form a part of the invention of this application.

The base or bottoms of the channel I isformed with flanges 8, 9 and I0, vertically disposed and spacing the bottom of the channel from the sill A. Near the outer ends of the bottom of the channel I are the weep holes II which communicate with the outer sub-channel I2 of the channel member and the flange 8 is formed with lateral weep holes shown in dotted lines at I3, through which water trapped in the channel will pass to the outer side of the window and Weatherstrip construction;

The bottom or zinc plate beneath the channel member I, as has been previously referred to herein, is designated I4, and really forms the bottom of the outer sub-channel I2, though it extends partly at its inner edge into the inner subchannel I5, beneath the channel member I. This bottom plate I4 is seen best in Figure 3, as being equippedat its inner edge with an upwardly and downwardly resilient member or flange I6 of somewhat V-shape in cross section, the sides of said flange or resilient V-member being compressible toward each other. The outer side of the member l6 engages with the inner side of the flange 9, depending from the bottom of the channel member I and the inner side of said member I6 is adapted to be engaged and pressed against by the screw or similar fastening I1 used for at' taching the channel member I to the sill A.

The action of the parts I! and I6 and I4 will be quite apparent upon brief reference thereto. The

operation of screwing home the screw I1, attaching the channel member I in place on the sill A, tends to push against the inner side of the resilient V-member I 6 and by doing this tends to force the V-member outwardly from the stool B to cause its outer side to snugly hug or flt against the inner side of the flange 9 of the member I. It is notable that the right hand or inner side of the V-member I6 extends downwardly and has its edge terminating in a plane slightly below the plane of the plate I4.

The pressure of the flange 9 downwardly on the plate I4, as the screw I1 is screwed home in attaching the channel member I in place, causes the lower biting edge I6a of the member I6 to bite or sink into the wood of the sill A, thus establishing an air tight connection between the parts I 4 and A, and doing away with the need for placing a calking compound in the inner sub-channel I5. The action of the screw II againstthe member I6 as the parts are placed and secured in proper position on the sill, will always tend to shift the plate I4 to its proper position illustrated in Figure 1, beneath the channel member I.

Now when the channel member I is of the type used in the manner illustrated in'Figure 1, not

only does the screw I! act on the parts I6 and plate I4 in the manner stated, but the V-fold of the member I6, as the screw I1 is screwed home, tends to push the screw against the inner side of the opening in the bottom of the channel member I through which the screw passes. Naturally this pushing action tends to force the channel I snugly into the corner provided by the angle between the sill A and the stool B. The member I6, under the above conditions, will now be seen to act with a double function, namely, exercising a pushing effect outwardly upon the plate I4, and an inward pushing effect. upon the channel member I, in conjunction with the coaction of the screw I1. r

In Figure 2, the construction of the invention dow which does not utilize the form of stool B 5 shown in Figure 1.

There is illustrated in Figures 4 and 5, a modified form of. the invention, in which I use a bottom zinc or plate I8 for the channel member which is formed with an up-turned V-flange I9 instead 17 of the down-turned type of flange shown in Figures 1 to 3 inclusive. The flange I9 has the resilient function of the flange I6 so. as to accomplish the same results in so far as tending to force the plate I8 outwardly and the channel member I in- 15 wardly in the action of driving home the screw or fastening I1. 01 course, the equivalent of the biting edge I6a is not provided in the construction of the bottom plate I8, with its V-flange I9.

From the foregoing it will be apparent that I 20 have devised a special bottom zinc or plate for my channel member type of eatherstripping of quite simplified construction but ensuring a proper positioning of the bottom plate in the assembly and attachment of the same and the channel member to the sill.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:- V
